I am adding a sub to my stock system. Whats the easiest way to do this since our decks have no pre-outs. Tap into the existing sub wires? Any info would be appreciated.

 

You need a special adapter to match the levels of the Bose system. Go to www.peripheralelectronics.com . You will need a Vendetta piece - basically taps in to speaker wire and gives you a line level out signal. Then, choose an amp. A good specialty car audio shop or Circuit City or Best Buy (yea believe it or not they know what they are doing with this type of thing) can do it for you, if you are no a DIY.
